Good guess. Well, I'm not exactly sure where it is. The photo is from about 1974 and the general location is Florence, It.  We were on one of those tours that covers a lot of territory in a short time so the guides were attempting to show us the extensive art scene.  My impression is that this house or mission was where a Renaissance painter "happened" to "scribble" a masterpiece or two on the walls.  I will continue to look for the exact place details.  I reviewed 1600 photos of Florence on line without finding it.  Unfortunately, most were photos of the Ponte Vecchio (that I also have) or some other famous landmarks, but nothing of my less known site.
